So, just like a moving mass has kinetic energy = 1/2 mv^2, a coil carrying current stores … WebAug 27, 2024 · Multiply watts by seconds to get joules. A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you’ll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.
